Sources: 6. Developments: 2. Florida is engaged in multiple legal actions concerning property insurance and risk assessment methodologies. Attorney General James Uthmeier filed a lawsuit against First Street Technology Inc., alleging that the firm’s climate-risk modeling is deceptive and based on flawed science. The state claims these “alarmist” scores, which assess exposure to floods, fires, wind, and extreme heat, contradict federal FEMA data and negatively impact the real estate market by depressing home sales and increasing insurance costs. First Street maintains that its methodologies are validated and based on the physics of environmental perils. In a separate matter, the Florida Supreme Court issued a unanimous ruling regarding insurance policy litigation. The court determined that homeowners with policies issued before July 1, 2021, are exempt from new pre-suit notice requirements when filing lawsuits against insurers. ## Timeline ### 2026-10-28: Florida legal disputes involve insurance rules and climate risk data Florida legal developments include a Supreme Court ruling protecting older insurance policyholders from new notice rules and a state lawsuit against First Street Technology over alleged deceptive climate risk's 2 sources. https://clstr.news/cluster/florida-legal-disputes-involve-insurance-rules-and-climate-risk-data ### 2026-10-26: Florida sues First Street Technology over climate risk scores Florida Attorney General James Uthmeier is suing First Street Technology, alleging its climate-risk property scores are alarmist, inaccurate, and unfairly depress home values and sales. 4 sources. https://clstr.news/cluster/florida-sues-climate-modeling-firm-first-street --- Cite as: Florida legal disputes over insurance and climate data.
